IM PROVEM ENT IN STOVES.

Specification forming part of Letters Patent No. 203,528, dated May 14,1878 application filed November 26, 1877.

Improvement in Stoves. which improvement is fully set forth in thefollowing specification, referencebein g had to the accompanying draw'in gs.

The object of my invention is to construct a stove that shall combineall the advantages of a common stove with one that has tubes running upthrough the {ire-box to discharge currents of hot air into the room, andalso to make it interchangeable from one to the other, either Wholly orin part.

To do this I make either the side plates b or the doors d, or both,corrugated by means of the ribs c. When the doors d are closed againstthe ribs c on the plate b, tubes or airpassages are formed.

The air passes from the air-box a on the under side of the stove,through the holes in the bottom of the stove, into the air passagesformed by b c d, and up through the holes in the top of the stove intoan upper air-chamber, E, where the discharge is regulated by means ofdampers. (Not shown.)

The air-chamber c is supplied with fresh air by a tube running down fromit through the licor, and thence to the outside of the building, and thedraft of the stove is supplied with air taken from the extreme portionsof the room or adjoining rooms by pipes ruiming under the door.

I also use a grate in the bottom of the stove, Which I make and place inthe following manner, viz: I groove the bars f of the grate G, and putthe two grooved sides together, forming tubes. The ends of these tubesin the grate G are placed in line with the holes h in the plates b ofthe fire-box, and the air is made to pass through them by means ofdampers. (Not shown.)

I claim as my inventionv The doors d on the outside of the stove Withthe ribs c on the outside of the plates b or the inside of the doors dwith the grate G, all of l which are made and combined in the Way andfor the purpose as substantially set forth in the above specification.
